Abstract

A humidity measuring device (10) is equipped with a temperature and humidity measurement unit (26) including a temperature sensing element that measures temperature and a humidity sensing element that measures humidity, a casing (12) having an accommodating section (20) in which the temperature and humidity measurement unit is accommodated, and a supply tube (22) that supplies a gas at a measurement location into the accommodating section, and a display unit (14) having a display device (54), and which is fixed to the casing. The display unit (14) further includes a display control unit (52) that controls the display device (54) to thereby cause the display device (54) to display at least one of the humidity of the gas measured by the humidity sensing element, or a dew point temperature of the gas calculated based on the temperature of the gas measured by the temperature sensing element, and the humidity of the gas measured by the humidity sensing element.
